服务器上最近输出 "PHP message: PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0" while reading response header from upstream 会持续拖慢服务器

按资料说 修改php.ini ;max_input_vars = 1000 参数。总感觉修改这块配置不是最好的方法,有有相关经验的吗

错误警告已经很明显了。你感觉改那个配置不是最好方法的原因是,万一下次有 10000 个参数了呢,又得改配置吗。所以你得从源头上查一下,为什么一个 post 会有那么多数据,有没有优化的点。

这是php5.3之后的一个新东西。用于解决之前一个海量参数引起的内存溢出的bug。
你应该从源头上看看是怎么回事,然后尝试去优化源头,我们以前也遇到过这个问题的。。就是论坛保存各个板块设置的时候,实际上是一次把所有数据都保存了。。结果就导致了这个错误。后来通过优化业务逻辑。搞定了这个问题。
这个不单是会提示错误,还会截断后面的数据。。例如原始是200个。你post了201个元素。那最后一个元素就丢了。
